tain new and useful Improvements in Rowboat-Motors, of which the following is a,

specifciition.

This invention relates to a rowboat motor and is particularly directed to the malhlier of supporting the inotor iipon e rowboiit or the like and to the manner of controlling the direction and speed of the craft.

i A particular object of the invention is to provide' means 'whereby the motor may be free'to swing to :use fe position in cese an obstruction is encounteredbythe propeller or adjacent parts. .v

'A further object is to provide ineens whereby the .iibove, object may eccomplisl'ied without inter ering with the .device or devices by which the motor is niedeadjiistablc to suit different requirements of posltiony upon e rowboat or.:thevlike.

' A further object is to provide means for y.controlling the angular disposition ofthe 1blii'des ofthe propeller, and' therefore theA peed Vand d ir l.ietion of the craft; so that'seid itself to Y e unnatural control'lans'will be free to accommodateA` nietbyt propeller .oradjecent parts. a

wise provided with an offset portion 14'for the same purpose. The offset portions 14 incidentally serve to indicate to the opelirtor exactly where the clam tached to the tail-board. hemthus serve tocenter the clamp on the tail= ard.

Suitable extensions 16 are provided for' forming pivotal connection with the ref mainder of the Structure 'as at 17.

AThe pivotal connection at 17 is made with an auxiliary frame 18 which is in turn pivotally connected as at 19 to a part rigid This auxiliary frame continues from the pivotal connections 19 downwardly beyond the pivotal connection 7 and carries a pair of segmental guide bars 20 arranged concentric to 'the Nota/l connection 19.. The guide bars are formed with slots 21 for engnge'ment t; 'a clamp screw 22 carried b7 t estandar L through the medium of W ich the standard may be held in any adjusted position along the guide rods relatively to the frame 18 in the customary' manner.

In order to retain the auxiliary frame 18 normally fixed to the bracket clamp l0 and yet al'ord ameans whereby it may heed to swing about the pivotaly connection 17, when occasion arises, u spring pressed lug is provided for the bracket clamp in a yposition to engage within a seat formed in a projection 24 provided upon the auxiliary Iframe. The auxiliary frame will thus be "held by friction under normal circumstances but will be free to swing outwardly when undue force is brought to bear upon the lower end 'of the standard.

It will thus be seen that any degree of adjustment relatively to the vertical may be given the standard through the medium of the pivotal connection 19 and the. guide bars and such an adjustment positively maintained by means of the clamp screw 22.. This adjustment is independent of the pivotal connection between` the auxiliary frame and the `bracket clamp.

When the lowerend of the standard strikes an obstruction in the river bed, or when for any reason undue backward ressure is applied to the lower end o the standard, lthen the frctional connection be-l tween the spring catch 23 and the auxiliary 'rame will be released and the auxiliary frame with all ofthe remainder of. the vice, excepting the bracket clamp, about the pivotal connection 17 into the Fig. 1. j

On account of the fact. that the' control handle' 8 project-s' forwandly Aand lis liableto damage when the standardassumes they position shro-Wn in dotted lines'in F ig. 1, 1t is desirable that .a means be provided to avoid injury to the control lilaxidle, Such a means is illustrated in Figsfyto 7 fand the' dewill swing toward. or position shown dotted lines inv i should be at:A

same includes provisions whereby the control handle is made capable of bending without injury.

The structure shown in Figs. 4 to T comrises a oke 25 which spans the standard i and ta es the pivotal connection E). The rear end of the yoke is ivotully Connected as at 26 to the upper en of the rod T. The forward end of the yoke is provided with a tubular extension 7 Aca'i"'r}`fiiig a movable plunger 28, A'is'pllhg' Q9 is arranged within the extension topyes's the lun er backwardly toward the standard ant into ensagement with thel teeth ofv 'ti-.rack 30., The enter end of the plan r Qs carries a cross pia ai which constitu es apu'fotal cenato non for the hand grip part et the control hand-le, which part is sepanuely termed eau independentl yoke about t e npin 31.

The hand gr1p p rt furcated und proy'ldtlnwiti extensions 32, which .continue along the sides of the ex tensione?. 'e extension 27 is cylindrical und the hand rip part is freely rotatable thereabout. Vhen the hund grip art is rotated into a position in. which tie pin 31 is horizontal then said hnn'd grip part is 25 and'throug the same to the rod 7. e c y ip part 'will be directl ti, l

In order to maintain the hand grip part normally in alinement with the yoke 25 when the pivot pin 31 is in horizontal position, the extensions 32 are arranged to engage against conceved shoulders 33 formed at the base of the extension 27. The spring 29 serves to hold the parts 32 against the shoulders 33 at all times.

The frietional connection thus afforded be- `tween the hand grip part andthe yoke is preferably sullivcient so as to cause thedownward movement of the rod 7 prior to the'giving way of the tween said handy By'this means 'the angular disposition of the propeller blades will be automatically changed so as toltend to pull backward and there y assist in theupward movement of the lower end of the standard L.
